COM (Serial) Ports
COM1 to COM4 can be selected among RS232, RS422 and RS485. In addition, COM1 and
COM2 can be switched between standard RS232 and RS232 with power. For pin definitions and
jumper selection of different communication modes, please refer to Chapter 4.
The serial ports are asynchronous communication ports with 16C550A-compatible UARTs that
can be used with modems, serial printers, remote display terminals, and other serial devices.
•
BIOS Setting
Configure the serial ports in the Advanced menu (“Super IO Configuration” submenu) of the
BIOS. You can use the BIOS setup utility to configure RS485 auto flow mechanism. Refer to
Chapter 7 for more information.
